Mh. Chou et al., 1.5-mu m-band wavelength conversion based on cascaded second-order nonlinearity in LiNbO3 waveguides, IEEE PHOTON, 11(6), 1999, pp. 653-655
We report wavelength conversion and spectral inversion using cascaded secon
d-order nonlinearity in periodically poled LiNbO3 waveguides pumped at 1.5
mu m. The converter has an internal conversion efficiency of -8 dB, a conve
rsion bandwidth of 76 nm, and a constant conversion efficiency for the 50-d
B range of signal powers tested.
